Engine oil Mannol or OEM Audi

Any oil that meets the manufacturer's specification for your car will be fine. Mannoil 5W30 fully synthetic meets VW 502.00 and ebay sell 5L for about £17 - why pay more?

Definitely better well known brands out there for cheaper prices. Look at Mannol oil. Mannol served me well.

I use Mannol. 5l of the stuff in 5w-35 retails at about £20 on eBay which is a damn good price.

I've always had good luck with manol oils.

Oi analysis came back and no extra signs of wear... Mannol is great oil just change at 5k and add in oil additive such as ceratec every other change

I've used for the last 20k miles and no problems! Just change at 5k.

Also been using Mannol. Do 6k oil changes though. Made chain noise on start up. Swapped back to mannol noise gone.

I've used Mannol for a few years, it's dirt cheap here in the UK and I've never had any issues with it.

I had the same issue on my 2019 A6 3.0 last year. Two times I had to pop into the dealership to have oil removed (no charge) and the issue was due to dilution and short trips.

I've just drained this from my car after 6700 miles. I'm not very impressed TBH. The car burnt about a litre in that time, it usually doesn't use half that
